TPS51200-Q1: Support for DDR4 memory

Vivek Kalkur

Part Number: TPS51200-Q1
Other Parts Discussed in Thread: TPS51200

Hi, we are using DDR VTT termination regulator part# TPS51200QDRCRQ1 with DDR4 RAM part# MT40A256M16LY-062E AUT:F . Datasheet of TPS51200-Q1 mention support for "low power DDR3 & DDR4". Let me know if this regulator works for the said DDR4 part?

Thanks,

Vivek

Hi Vivek,

The TPS51200 is suitable for DDR4 applications and the datasheet shows how to configure the device for DDR4 (See Figure 30 in the datasheet). I am not familiar with the specific RAM device you mention, but I did a quick online search and find an example schematic using both of these devices together in a system.

Best regards,

Matt

Hi Matt, thanks for your reply. I checked Figure 30 in datasheet, it is for DDR3 tracking configuration, not DDR4. Did you mean to Refer Figure 29 for LPDDR3 or DDR4 in datasheet?

Also, iam feeding 2.5V for VIN pin instead of 3.3V supply recommended in application circuit (Figure 29 in datasheet). Please review the circuit diagram below and confirm whether this is suitable for DDR4 applications.
